Plan and implement an Azure Virtual Desktop infrastructure

Your network contains an on-premises Active Directory domain that synchronizes with an Azure Active Directory (Azure AD) tenant. The domain includes the domain controllers shown in the following table.

Question Image

The DNS servers are configured to forward requests to an external DNS service.

You create a new virtual network named VNET2, which is peered with VNET1 and has gateway transit enabled.

You plan to deploy an Azure Virtual Desktop host pool in VNET2. The session hosts will join the Active Directory domain.

You need to configure DNS to meet the following requirements:

  • Ensure that Azure Virtual Desktop users can resolve on-premises servers and Azure resources.
  • Ensure that Azure Virtual Desktop remains operational if a DNS server fails.
  • Minimize administrative effort.

What should you configure?

  • A the DNS settings of VNET2 to use Server2 and Server1
  • B the DNS settings of VNET2 to use the Azure DNS service
  • C the DNS settings of the virtual machines to use Server2 and Server1
  • D the DNS settings of the virtual machines to use the Azure DNS service
Explanation

Custom DNS is required so the domain-joined session hosts can resolve the on-premises Active Directory namespace. Configuring VNET2 to use Server2 and Server1 applies the DNS configuration network-wide to the session hosts, rather than requiring configuration on each virtual machine. The DNS servers can resolve domain names and forward other queries to the external DNS service, while listing both servers provides resilience if either DNS server fails. Microsoft recommends network-wide DNS settings where possible and identifies customer-managed DNS servers as a solution for resolving on-premises names from Azure virtual machines.
